采用人工污染土壤法测定了不同浓度阿苯哒唑对蚯蚓生长、生存、繁殖以及超氧化物歧化酶(SOD)、谷胱甘肽-硫转移酶(GST-S)、乙酰胆碱酯酶(AchE)活性的影响.结果表明:低浓度阿苯哒唑(5mg·kg^-1)对蚯蚓的繁殖有显著的抑制作用(P〈0.05);当阿苯哒唑含量达到7mg·kg^-1时,将明显影响蚯蚓的生长和生存(P〈0.05);当其含量达到10mg·kg^-1时,蚯蚓的死亡率为53%.阿苯哒唑浓度与蚯蚓的生长、繁殖间存在明显的剂一效关系.阿苯哒唑染毒21d后,对蚯蚓SOD、GST-S的活性有明显影响,药物浓度与效应间没有明显的剂-效关系,对AchE活性没有表现出明显的影响.阿苯哒唑对土壤动物显示毒性作用,具有潜在的生态风险.
By using artificial soil test, the effects of different concentration albendozole on Eisenia foetida's growth, survival, reproduction, and'activities of superoxide dismutase (SOD), glutathi-one-sulfurtransferase (GST-S) and acetylcholine esterase (AchE) were studied. Low concentration (5 mg·kg^-1 ) albendazole inhibited the reproduction of E. foetida significantly (P 〈 0.05), and 7 mg·kg^-1 of albendazole had significant effects on the growth and survival of E. foetida. When the albendazole concentration reached to 10 mg·kg^-1, the mortality of E. foetida was as high as 53%. There was a significant dose-response relationship between the exposure concentration of albendazole and the inhibition rate of E. foetida' s growth and reproduction. After 21 days' albendazole exposure, the SOD and GST-S activities were affected significantly, but no significant doseresponse relationship was observed. Albendazole exposure had less effects on AchE activity. In sum, albendazole had direct toxicity on soil animals, with a potential ecological risk.
